One of the most simple and function finish line devices can
be made with a LARGE display CALCULATOR and some swithces
at the finish line. You need to be able to solder simple
connections and mount the switches. Lane wire - is wired
to the calculator at BUTTON #1, lane two to # 2 etc.
Before each race - hit clear ! When the cars hit the switches
at the finish - the ORDER of finish will show on the calulator
display. Total cost - less than $20.
